Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29312, here are decompositions:

  • 43 + 29269 = 29312
  • 61 + 29251 = 29312
  • 103 + 29209 = 29312
  • 139 + 29173 = 29312
  • 181 + 29131 = 29312
  • 211 + 29101 = 29312
  • 379 + 28933 = 29312
  • 433 + 28879 = 29312

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 29312 first appears in π at position 121,752 of the decimal expansion (the 121,752ordinal-suffix:nd digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
